Okay, so a buddy of mine told me of the best way in the world to change power steering fluid. Requires no special tools or equipment, just get a gallon of Power Steering Fluid (Valvoline sells it) and a plastic cap (buy an assortment of vacuum line caps).

Jack Up/Support front of vehicle. Tires must be off the ground.

Remove return line to power steering fluid pump (it's the one without the pressure fitting, just a regular old hose clamp).

Quickly cap off the metal line on the power steering pump with a vacuum line cap.

Place end of return line into a mason jar. You might want to have a friend hold it there for you.

Fill power steering reservoir to the top.

With the engine off turn the steering wheel all the way in one direction until it hits full lock.

Notice how much dirty fluid has been spit into the mason jar.

Top off power steering reservoir.

Turn steering wheel all the way in the other direction.

Top off power steering reservoir.

Repeat this procedure until the fluid comes out clean. It took me about 3 quarts.

One complete set of turns of the wheel (from lock to lock) will bring the power steering fluid level down from the top of the reservoir to approximately a good "Fill Cold" point. Be sure to check the level to make sure.

My steering feels great now. Definitely a noticeable differnce. Also, it's nearly silent. I would recommend it to all.

Power steering fluid is one fluid that gets forgotten by most.

Thanks for the change out info.

Tell me about it. I'm not super religious about checking fluids but always before long trips or towing. Unfortunately I haven't had the pleasure lately so after my steering started acting up I looked at everything except, of course, the fluid level. I checked it tonight, along with all the others...what do you know, low power steering fluid. Added fluid, problems solved. Apparently I've forgotten that a few times since I do know this truck has needed a bit of fluid here & there over the years. DUH!!!!

Every other year or so I just suck all the fluid out of the reservoir and refill.

i was going to try the turkey baster method(i don't have jacks, and don't feel like cribbing my truck up) but i was told GM dosen't recommend touching the p/s fluid...and i'm afraid if i change some of it that it will increase of my risk of a leaky rack

Getting ready to drain and refill the power steering fluid this summer and I found this procedure:

http://www.thetrucks...-steering-fluid

Any chance of damaging the pump running it dry even if you shut it off right away?

The procedure is a little more than half way down the page...
